And I've seen plenty of people who turn on 'hands free' mode and then hold the phone a few inches away from their head.

For when an Amazon drone just isn't fast enough.

Cortana, Spartan, now this.

You just know that people with no kids would buy that too, just so that they could re-enact launching a missile every time the kitchen towels were running low.

The same-day Amazon Fresh service seems to have such thing (I found it when searching to see if this new product was a joke).

You mean like Alt-Space M or Alt-Space S in Windows?

I searched for "confirmation bias is false" and got lots of hits. so what's your point?

Yes, my wife mentioned reading about a similar situation recently. This must be it

You can't really know who that person will become in future years well enough leave a meaningful message. Better to just create some good memories now.

In this case state that you only accept applications encrypted to your public key.

For a while, at least, the installer from winscp.net included an installer for other bundled software.

findimagedupes builds a database of fingerprints (basically a scaled-down monochrome image) and can call an external program with the matching duplicates. You could read the resolution in the external script using jhead or exiftool.

Yes, I first heard of similar devices decades ago. Back in the 70s, I think, there were handheld units and I remember seeing a sonar system built into spectacle frames (I don't know if it was a practical design, not sure how it was powered).

I think that the story here is that it's cheap and built into a watch, although I'd have thought that a handheld device would still be better for aiming as well as battery life.

"Reaction time is a factor in this, so please pay attention. Now, imagine you see some children on your lawn. What's your reaction?"

It depends on how the app works.

Does it work like an old-style program that performs some computation and does something, or is it a 'cloud'-based app, i.e. it sends all the raw data off to some server somewhere?

Given that it is said to send an email instead of just display a notification, I suspect the latter, in which case you're sending those potentially 'followers only' tweets off to a third party.

Yes, if either via a separate program or as part of an existing service, everyone had a personal mailing list, the 'social network' aspects would be separated from the transportation method. You would 'follow' someone by sending them a subscribe message (or your app would do it when you clicked a button).

A reader could display a digest of all such mails from the people you follow (maybe sorted by tags added to headers).

Someone without any specialized program could still subscribe and get your mails. Conversely a webmail service like GMail could dress it up to look G+, where someone replying to one of your messages would appear as 'posting on your page'.

The initial draw of a social network is the ease of broadcasting your (possibly inane) thoughts to everyone who wants to hear from you. You don't do that to everyone in your contact list because they've not signed up to know what you had for breakfast. A way of collecting a willing audience is all that's needed.
